SPECIFICATION forming part of Letters Patent No. 551,410, dated December 17, 1895. Application iiled July 5,1895. A Serial No. 554,997. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANK P. SHEPARD, a citizen of the United States, residing,` at Edmond, in the county of Oklahoma and Territory of Oklahoma, have invented a new and useful XVindInill, of which' the following is a specification.

The invention relates to improvements in windmills.

The object of the present invention is to improve the construction of windmills, and to provide a simple one, which maybe cheaply and conveniently manufactured, and in which the vane will operate as a weight for holding the wind-wheel into the wind.

The invention consists in the construction and novel combination and arrangement-of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a side elevation of a portion of a windmill constructed in accordance with this invention. Fig. 2 is a front elevation of the saine. Fig. 3 is a side elevation, the wind-wheel being thrown out of the wind. Fig. 4 is a plan view. Fig. 5 is a detail sectional view, illustrating the manner of journaling the rotary standard or support at the top of the tower. Fig. (l is a detail view, illustrating the manner of bracing thc blades of the wind-wheel.

Like numerals of reference indicate corresponding parts in all* the figures of the drawings.

1 designates a rotary standard or support,

, disposed vertically, and journaled in the upper portion of a tower 2, and adapted to rotate therein, vto perform the function of a turntable. The rotary support or standard is composed of parallel sides 3, connected at their lower ends by an interposed block 4C, and depending from the block is a tubular journal or pivot 5, which is arranged within a suitable bearing of the tower 2, a washer 6 and a coliar 7 being interposed between the bottoni of the block e and the supporting portion of the tower 2, to lessen the bearingsuriace, to decrease the friction, and to prevent wear of the parts. The upper ends of the sides 3 of the rotary support or standard are connect-ed by horizontal bars S and 9,

vided.

which are connected by suitable cross-pieces, and which are supported by an inclined brace 10; and the bars 8 and 9 and their connecting cross-pieces forni a frame at the top of the rotary standard or support to receive a windwheel shaft 11.

The wind-wheel shaft 11 is disposed horizontally, and has mounted on its outer poi-,

tion a wind-wheel 12, which is secured between an inner collar or flange 13 and a pair of nuts 14, one of the nuts operating as a jam-nut to prevent the other from accidentally unscrewing.

The wind-wheel, which may be of any desired configuration, may be conveniently construct-ed by mounting blades l5 on a light vehicle-wheel 1G. A blade is preferably arranged at each spoke of the vehicle-wheel lo, and is composed of two longitudinal sections connected by cleats and located adjacent to the spolgesat opposite sides of the riin or telly, and the blades are set at the proper angle and are supported by connecting-braces 15:L and 15"'. The transverse cleats which connect the sections of the blades are located at the inner and outer ends thereof, and also at the centers of the blades at the periphery of the wheel 1d. The braces l5 and 15b are constructed of strap iron or inetal. The braces 15b are arranged at the outer ends of the blades and are disposed transversely of the wheel extending from the outer edge of one blade to the inner edge of an adjacent one, and the other braces 15 connect the ends of the blades and are arranged at the periphery of the wheel 12, extending entirely around the saine at opposite sides thereof. The blades are also connected by short braces 15C, each extending from the outer edge of one blade to the center of au adjacent blade and located adjacent to the riin of the vehicle-wheel.

In order to enable the support or standard 1 to rotate frictionlessly at the top of the tower, which is provided with a circular opening 17, an annular series of rollers 1S are prorlhe rollers are disposed vertically and bear against the top of the tower at the edge of the circular opening 17, and are j our-A naled in suitable bearings, preferablyforined by upper and lower blocks 19, secured to the IOO yIO

outer faces of the sides 3, and horizontal bars 2O interposed between the sides3and projecting'beyond the same, as shown.: The horizontal wind-wheel shaft carries a sprocket wheel or pinion 2l, and is connected by a sprocket-chain 22 with a crank-shaft 23, and the latter has a sprocket-wheel 24 of greater diameter than the sprocket-pinion 2l to receive the chain A suitable pumprod is designed to be connected with the crank-shaft, as will readily be understood, and the horizontal bars 2O are provided with pump-rod openings 25. The windovheel is held into the wind during the operation of the windmill by a vane 26, provided at its inner end with a centrallyarranged arm 27, provided with an eye, which is hinged to a corresponding eye 2S of thebar 8 by means of an inclined pintle 2 9, which extendsv a'considerabl'e distance below the vane and is mounted in a block or support 30. The vane 26 is provided at the lower end of the pintle-rod 29 with an eye 3l, which is ycarried by a' downwardly-extending brace 32,

which inclines inward from the central portion of the vane.

The eyes of the vane and the stal'idard4 or support are set at an inclination to conform to the disposition of the pintle-rod, and the latter inclines downward and inward from one end of the bar S, the lower end of the pintle-rod not being disposed in the same vertical plane as the upper end, rbut being disposed nearer the center of the adjacent side 3 of the support. By this construction the vane 26 in swinging to a position parallel with the wheel is raised from the horizontal position which it occupies when the windmill is in operation to an inclined position, as clearly shown in Fig. 3 of the accompanying drawings, whereby it is necessary to ylift lthe vane vto throw the' windmill out o f the wind, thereby utilizing the weight of the vane for the purpose of holding' the wind-wheel normally in thel wind. The swinging of the hinged vane 2G away from the wind-wheel is limited by a staychain 33, which operates to prevent the vane swinging beyond the position at right angles to the wind-wheel..

'The wind-wheel is thrownv out lof the wind by means of a rope or other `connection 3e, havingon'e' end attached tothe vane and'e'x! tending over a pulley 35, and having its other end connected with the base of the tower by wire 3G, or.the li,ke,...The wire passes wind becomes too great for the windmill, and

the speed of the windmill is governed by the weightV of the vane, as will be readily understood.

It will be seen that the windmill is exceedingly simple and inexpensive in construction, that it is automatic in operation, and that the ,weight of the vane isemployed for holding the windfwheelinto thewind.,

, Changes in .the form, proportion, and the minor details of construction may be resorted to without departing' from the principle or sacrificing any of the advantages of this invention.

A windwheel comprising a vehicle wheel composed of a hub, spokes and a rim or felly connecting the outer. ends of the spokes, a series of radially disposed blades, each consisting of two longitudinal sections having their inner portions arranged at opposite sides of thevwheels adjacent tothe spokes, the transverse cleats connecting the sections of the blades arrangedat the ends thereof and at theperiphery. of the rinior felly, the annular braces l5 arranged at the periphery of the windwheel and located at .the side edges of thev blades, the braces l5b arranged .at the outer ends of the blades and extending transversely ofthe wheel from thel outer edge of one blade. to the inner. edge of the adjacent blade, and the short/,centrally arranged bracesv I5C extending from'the ycenter of one blade to the outer edge of. theadjacent blade, substantially as described. l n

jIn testimony vthat I claim the foregoing as my ownV I have hereto afxedmy signature in the presence of two witnesses.
